摘要
采用HNO3 —H2 O2 微波消解电感耦合等离子体质谱法(ICP-MS) 测定PP 餐盒中的铅含量,测定结果显示相对标准偏差为3. 8%,检出限为0. 05 mg/ L,结果表明该方法具有简便、快速、准确、灵敏度高等优点,适合于PP 餐盒中铅含量的测定。
Abstract
Lead in PP lunch box was determined by ICP-MS after microwave digestion with a mixture of nitric acid and hydrogen peroxide. The result showed that the relative standard deviation (RSD) is 3. 8%(n =6) and the detection limit is 0. 05 mg/ L. The method is accurate, simple, sensitive, and rapid for determination in PP lunch box.
